Add support for Accton as9726-32d platform This pull request is based on as9716-32d, so I reference as9716-32d to create new model: as9726-32d. This module do not need led driver to control led, FPGA can handle it. I also implement API2.0(sonic_platform) for this model, CPLD driver, PSU driver, Fan driver to control these HW behavior.

|
The code for integacting with Accton AS9726-32D has 2 parts,
|
|
kernel drivers and operational script.
|
|
The kernel drivers of peripherals are under module/ directory.
|
|
1. These drivers are at module dir.
|
|
2. A operational script, accton_as9726_32d_util.py, for device initializatian and
|
|
peripheral accessing should be installed at /usr/bin.
|
|
Run "accton_as9726_32d_util.py install" to install drivers.
|
|
|
|
To initialize the system, run "accton_as9726_32d_util.py install".
|
|
To clean up the drivers & devices, run "accton_as9726_32d_util.py clean".
|
|
To dump information of sensors, run "accton_as9726_32d_util.py show".
|
|
To dump SFP EEPROM, run "accton_as9726_32d_util.py sff".
|
|
To set fan speed, run "accton_as9726_32d_util.py set fan".
|
|
To enable/disable SFP emission, run "accton_as9726_32d_util.py set sfp".
|
|
To set system LEDs' color, run "accton_as9726_32d_util.py set led"
|
|
For more information, run "accton_as9726_32d_util.py --help".
|
|
|
|
====================================================================
|
|
Besides applying accton_as9726_32d_util.py to access peripherals, you can
|
|
access peripherals by sysfs nodes directly after the installation is run.
|
|
|
|
System LED:
|
|
There are 5 system LEDs at the lower-left corner of front panel.
|
|
They are loc, diag, psu1, psu2 and fan.
|
|
The sysfs interface color mappings are as follows:
|
|
Brightness:
|
|
0 => off
|
|
1 => green
|
|
2 => amber
|
|
But not all colors are available for each LED.
|
|
|
|
Fan Control:
|
|
There are 12 fans inside 6 fan modules.
|
|
All fans share 1 duty setting, ranged from 0~100.
|
|
|
|
Thermal sensers:
|
|
6 temperature sensors are controlled by the lm75 kernel modules.
|
|
|
|
PSUs:
|
|
There 2 power supplies slot at the left/right side of the back.
|
|
Once if a PSU is not plugged, the status of it is shown failed.
|
|
|
|
There are 32 QSFP56-DD and 2 SFP+ modules are equipped.
|
|
Before operating on PSU and QSFP+, please make sure it is well plugged.
|
|
Otherwise, operation is going to fail.
